DAVID MURTEA, OF PHILADELPHIA, PENNSYLVANIA.

BRICK-MACHINE.

specification forming part of Letters Patent No. 42.680, dated May10,1864.

To ali whom it may concern.:

Be it known that I, DAVID MURTHA, of the city and county ofPhiladelphia, in the State of Pennsylvania, have invented a new andImproved Brick-Machine; and I do hereby declare the following to be afull and exact description of the same, reference being had to theaccompanying drawings, making part of this specification, in which-Figure 1 is a perspective view of my improved brick-machine, and Fig. 2is a vertical longitudinal section of the same.

Similar letters of reference indicate correspending parts in bothfigures.

This invention consists, rst, in a peculiar construction offeeding-table, which, besides conveying the clay to the action of thecutting apparatus, facilitates the removal of the bricks; second, in anovel arrangement of rotating disks, whereby the clay is severed intopieces of the proper dimensions and shape to constitute bricks.

In order that others skilled in the art to which my invention appertainsmay be enabled to fully understand and use the same, I will proceed todescribe its construction and operation.

In the accompanying drawings, A may represent a frame which supports thevarious operating parts, and upon which is constructed a box orapartment, B Bl B2 B3, into which the clay is deposited. Within this boxis placed a follower, C, which is attached to and moved by a hollow rodor sleeve, D, which in turn is advanced and retracted by a screw orthreaded shaft,D'. This shaft D' has its bearing in the transverse pieceB5, and on its end is secured a band-pulley, D2, through the medium ofwhich the shaft D may be rotated, and thereby made to operate thefollower C. The pulley D2 may be turned by means of a. suitableconnection with a steam-engine, by horse-power, or in any otherdesirable manner.

`E represents the frame of a feeding-table, E, which moves upon ways A',formed on the frame A. The table E occupies a position be neath the boxin which the clay is placed, and is composed of a series of transversesections, e, which may be removed and replaced, for the purpose to behereinafter referred to. On the under side of the table E is a rack, E2,in connection with which is employed a pinion, F, whereby thefeeding-table E is propelled or advanced. The pinion F is mounted upon atransverse shaft, F', which receives rotation from the screw D throughbevel cog-wheels G G and band-pulleys .H H simultaneously with themovement of the follower C. The form of the box B B B2 B3 is clearlyshown in the drawings. Between the lower end of the sloping piece B3 andthe bottom B is an open ing, b, which may extend entirely across thebox, the vertical width of the said opening being such that when theclay is forced through the same it will be mol-ded or compressed into asheet of the thickness of which the bricks are to be made.

I may represent a series of knives or disks secured upon a transverseshaft, 1,which,with the disks I, is mounted and rotated in suitableproximity With the aperture b. These disks I are arranged at suchdistance with relation to each other as to adapt them to divide the clayinto pieces or strips, whose transverse width shall correspond with thelength of the bricks. J represents another series of disks,

which are mounted upon a shaft, J', and placed at right angles to thedisks I, the rotating shaft J with the disks J being made to movetransversely in Ways K K. The disks J sever into bricks the pieces orstrips formed by the disks I, and may be operated by hand or through themedium of suitable gearing.

After the clay has been deposited in the box B B B2 B3 the latter isclosed by a lid, B4, which may be firmly secured in position by rods bb.

The operation of the machine will be readily understood from thepreceding description. When the box B B Bz B3 has been filled with clay,the follower C is advanced in the manner described, and the table Esimultaneously moved for-ward beneath the opening b and the cuttingapparatus I J. As the clay passes out at the opening b, it is receivedonto the table E, and thereby conveyed to the action of the disks I J.As soon as the clay reaches a proper position to be severed by the disksJ, the movement of the table E is arrested by a gage, which may be soadjusted as to cause the sections e to occupy positions directly bctweenand beneath thedisks J, so that when the bricks are formed they may beremoved in separate quantities upon the several sections e.

It may be remarked that two, three, or more feeding-tables E may beemployed in connection with the machine, so as to render the operationthereof eontin nous, as represented in Fig. 2.

Having thus described my invention, the following is what I claim as newand desire to secure by Letters Patent:

1. The rotating disks I, arranged and operating in the describedcombination with the aperture b, and employed to sever the sheet of clayinto strips of Width equal to the length' of the bricks, as set forth.

2. The rotating and traversely-movin g disks vJ', operating to sever thestrips into widths for bricks, as explained.

3. The sectional feeding-table E E e, constructed, operated, andemployed substantially as and for the purpose specified.

The above specification of myjmproved brick-machine signed this 10th dayof March, 1864.
